A few questions about video decode acceleration

[bridgman]

OpenGL can only handle the "render" part of the video pipeline (colour space conversion, scaling etc..) not the "decode" part (IDCT, MC etc..). Strictly speaking I guess you could do crude MC in OpenGL (some GPU settings would be wrong) but don't know if anyone has ever tried it.

For those wondering what what is possibly available for hardware acceleration should see this link on the xbmc wiki.

It is really complete, nothing too detailed about implementations but otherwise a good collection of techs.
